Make it rain. Make Snow. Make Earth Habitable.
Rainmaker builds and deploys audacious technologies that work with nature to create an abundant, habitable planet. We are modernizing proven cloud-seeding science with weather-resistant UAS, radar and satellite observations, numerical weather prediction, novel sensing and validation systems, and sustainable seeding technologies. We are building an integrated system to make more freshwater available to farms, ecosystems, and communities.
Our ambition is bold, but we pursue it with humility. We take on difficult problems in the real world with technical rigor, grit, integrity, and an openness to learning and course-correcting. We are hiring individuals with evidence of exceptional ability. If you want to build systems that endure, restore, and deliver the future we were promised, we want to hear from you.
The vehicle software team builds the software that operates Rainmaker’s cloud-seeding vehicles, connecting flight control, onboard computing, sensors, payloads, and ground operations. We work closely with electrical, mechanical, manufacturing, and flight operations teams to turn new hardware into reliable systems that can be built, deployed, and operated at scale. Our goal is to make every vehicle a dependable tool for delivering more freshwater where it is needed.
About the Role
You will own embedded firmware across Rainmaker’s vehicle and its integration with our onboard and ground control software systems. Your scope includes flight-controller firmware, power distribution, sensor and payload controllers, and the interfaces connecting those systems to onboard Linux software. You will take work from architecture and board bring-up through testing, manufacturing, deployment, and support in the field. We’re looking for a high-agency engineer who identifies what needs to happen, turns incomplete requirements into a clear plan, and follows through until the hardware works reliably in real operating conditions. This is a hands-on technical ownership role with the autonomy to shape the firmware architecture and the responsibility to deliver it.
What You'll Do
-
Own the architecture, implementation, and maintenance of all embedded firmware across the vehicle, including flight-controller firmware, power distribution, sensors, and seeding payloads.
-
Set firmware priorities, identify reliability risks and technical gaps, and drive projects from an ambiguous problem to a validated release.
-
Bring up new boards with electrical engineers: read schematics, validate interfaces, write drivers, and debug failures at the boundary between hardware and software.
-
Develop dependable device communication and command handling over CAN, UART, SPI, and I2C, with clear contracts for telemetry, timing, and fault behavior.
-
Integrate firmware with our vehicle software so commands, device state, and telemetry behave consistently from the microcontroller to the operator.
